Can you do only one urgent part first, like kitchen before griha pravesh, and the rest later?

Sometimes yes, but it depends on site readiness, measurements, material availability, and the exact date. A kitchen before griha pravesh may be possible only if design approval, measurements, production, and installation time are realistic. Please share the griha pravesh date, floor plan, kitchen photos, site readiness, and whether civil, electrical, plumbing, and tiles are already completed
